<p>A thermoplastic container, which is particularly useful for packaging meat, comprises a first polymeric layer, a second intermediate or tie layer, and a third polymeric layer. The first layer comprises an alkylene terephthalate or naphthalate polymer such as polyethylene terephthalate (PET). The first layer can include, in whole or in part, one or more homo-polymers, co-polymers, recycled polymers, or reprocessed polymers. The third layer comprises a non-polar thermoplastic such as high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), or a blend thereof. The intermediate layer primarily functions as an adhesive and as a compatibilizer/emulsifier/surfactant (CES), and comprises a grafted or backbone-based co-polymer or ter-polymer of ethylene, glycidyl acrylate or maleic anhydride, and optionally an acrylate co-monomer. <IMAGE></p> |
